T0 on whom it may concern.-

Be it known that I, JOHANN BOELSTERLI, a citizen of Switzerland, and a resident at Fiissen, Bavaria, Germany, have invented new and useful Improvements in Fliers and Drag Devices Therefor-for Spinning and Twisting Machines, (for which Letters Patent have been granted in the following countries, viz: In Switzerland, No. 262, dated January 7, 1889; in Germany, No. 46,930, dated May 9, 1889; in France, No. 191,604, dated July 4, 1888; in Belgium, No. 82,519, dated July 31, 1888; in England, No. 10,191, dated July 13, 1888; in Austria-Hungary,No. 38 and No. 2,915, dated November 4, 1888; in Italy, XXII, 23,775, and XLVII, 25, dated September 1, 1888, and in Spain, No. 8,493, dated September 14, 1888,) of which thefollowing is a specification.

The invention relates to apparatus for spinning, twisting, or doubling fibrous substances, &c., and relates particularly to the construction and arrangement of the flier.

The flier is independent of the bobbin-spindle and terminates in a tubular spindle, which rotates in or upon a fixed bearing. The fibrous substance passes through this tubular spindle or the bearing upon which it rotates over one arm of the flier, and, passing downward, is led round the half of the periphery of a ring connecting the ends of the flier-arms, and thence runs to the spool. The flier is rotated by the traction exerted by the yarn or thread which is being spun or twisted.

By this invention a stronger construction of the spindle and an easier access to it are secured.

As it is no longer necessary to unscrew or remove the fliers from the spindle, a great saving of time is effected.

The invention is applicable to all sorts and sizes of spindles and fliers.

Some of the most important ways of carrying out the invention will now be described.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in the several views.

Figure 1 is a vertical sectional view, taken on the line a; m in Fig. 2, of a flier constructed in accordance with my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a plan view showing the flier-spindle, its bearings, and the support therefor, and the braking device. Fig. 4 is a vertical section of my i1nproved flier mounted in a modified manner. Fig. 5 is a similar view showing the preferred manner of mounting the flier; and Figs. 6 and 7 are plan views to show more fully the braking devices of Figs. 4 and 5, respectively.

In the construction illustrated in Figs. 1 and 2 the spool-spindle 27 is rotated in fixed bearings by means of a pulley or wharve 89. At a little distance from its upper end. it carries a pla e provided with a binding device f, which is tightly engaged on the spindle, and in which the lower head of the bobbin or spool 32 is securely engaged. The binding device consists in a disk f, having upwardlyextending springs f, between and by which the lower flange of the bobbin or spool 32 is held. Other arrangements can also be used which can be easily disconnected and form at the same time a secure connection between the spool and the spindle. In this arrangement the flier a is independent of the spool and its spindle. The flier a is provided at its upper end with a vertical tubular spindle b, revolving in tubular bearings c 0, attached to a carrier or support g, capable of moving vertically. A spring braking device d is applied between the two bearings c c, in which the aforesaid tubular spindle rotates. A nut e or its equivalent applied to the end of the tubular spindle prevents it from shifting vertically in its bearings.

In the modification of the foregoing arrangement represented in Figs. 4 and 6 the nut e, which prevents the tube 2) from shifting in a vertical direction, serves also as a fric-. tion-disk, on the friction-surface of which the blocks of the brake d are brought to bear. In this case there is only one long vertical bearing 0 to guide the. tube.

In my preferred manner of mounting the flier, which is represented in Figs. 5 and 7, the vertical tube 19 forms a conical'bearing c which is engaged over a hollow wooden pin 1) and secured thereon by means of a nut so, applied to the lower end of the latter. This vertical hollow pin 1) is secured atits upper end in the bracket g by a set-screw 7c. The brake device d, employed in connection with the tube or spindle b, consists in two spring straps or arms secured to the bracket at their inner ends and provided with blocks or segments (1' between their ends to engage the opposite sides of the said tube. The outer ends of said straps or arms are apertured, and a screw h passes through the apertures and has at one end a thumb-nut h, by adjusting which the blocks d may be made to bear with greater or less force against the tube or spindle b. I use a similar construction of brake in connection with the spindle b in Figs. 1, 2, and 3.

In the construction shown in Fig. 5 the yarn comes in contact with the revolving parts when it has issued from the hollow pin 1). The path followed by the yarn is the same in the three arrangements. The material is led through the tubeb in Figs. 1, 2, and 3. Atter leaving pin b or tube 17 the thread passes over one of the guides 1 at the upper end of the flier, and thence, following a downward path along the corresponding arm of the flier, it passes over a projection 1; at its end and enters in the groove 2' of the ring i which connects both arms of the flier. The thread occupies only one-half of the periphery of this ring, whence it passes under the projection i of the opposite arm of the flier and over the ring i and finally onto the bobbin or spool.

While I have shown my flier in Figs. 1 and 2 in connection with a spindle, bobbin, and bobbin-holder, I do not claim the latter herein.

Having thus described my invention and the manner of employing the same, what 1 claim, and wish to have secured to me by Letters Patent of the United States of America, 1s

1. The combination, with the support g, the depending tubular bearing 19', the flier having an integral tubular spindle b, revoluble on said bearing, and the retaining-nut on the lower end of the bearing, of the brake-straps secured to support g, projecting at opposite sides of the spindle and provided with bearing-blocks d, and an adjusting mechanism, substantially as set forth.

2. The herein-described flier, consisting of the tubular spindle, the arms a a, the externally-grooved ring connecting the lower ends of said arms, and guides and projections 1' 4; at the upper and lower ends of the said arms, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHANN BOELSTERLI.
